I have searched a lot in this forum and in other sites, but I can't find this information. What is the maximum range covered by the Bluetooth module of ArduinoBT? In the datasheet of WT11 sheet, it is written "Class 1, range up to 300 meters" but, in my tests, I haven't been able to connect to an ArduinoBT if the distance between it and my computer is higher than 8 meters. I tried some different adapters with my computer, and some of them also had the same range in their specifications ("range up to 300 meters").
